ORA S. VILLETT, OF BELLEVILLE, KANSAS, ASSIGNOR OF ONE-HALF TO JAMES CUNNINGHAM, OF SAME PLACE.

WlNDMILL.

SPECIFICATION forming part of Letters Patent No. 360,188, dated March 29, 1887.

Application filed February 1, 1887. Serial No. 226,177. (No model.)

To all whom it may concern.-

Be it known that I, ORA S. \VILLETT, a citizen of the United States, residing at Belleville, in the county of Republic and State of Kansas, have invented a new and useful Improvement in \Vindmills, of which the following is a specification My invention relates to an improvement in windmills; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a top plan view of a windmill embodying my improvements. Fig. 2 is aside elevation of the same. Fig. 3 is a transverse sectional view taken on the line a; at of Fig. 1. Fig. 4 is a similar View taken on the line 3 y of Fig. 1. Fig. 5 is a detail view of the spider.

A represents the tower,which comprises the four corner-posts B, made of gas-pipe, the cap 0, to which the upper ends of the said cornerposts are attached, and the platform D,which connects the said corner-posts at a suitable height from the ground. In putting up the tower the corner rods or posts B are first passed through openings which are made in the platform D, near the corners thereof, and the upper ends of the said corner posts or rods are then sprung apart and fitted in openings which are made on the under side of the cap 0 to receive them.

E represents a hollow tubular sleeve, which passes through central vertical openings made in the cap and in the platform, and to the upper end of the tubular sleeve is secured the hub or spider F of the wind-wheel. From the said hub or spider projects a series of radial rods or arms, G, the outer ends of which are con nected to a circular band or tire, H. On each arm G is pivoted a wing or sail, I, and the said sails or wings are adapted to slide longitudinally on the said rods or arms and project from opposite sides thereof, though much the greater portion of the surface of each sail or wing projects from the lower side of its arm.

K represents a series of rods,which also project radially from the central hub or spider, the said rods being arranged substantially parallel with the radial arms G, and having their outer ends attached to cars or brackets L, that project from one side of the tire or rim. Near their inner ends each of the said rods K is bent at an angle of about thirty-five degrees with relation to the adjacent arm or rod G, the said angular portion of each rod K approaching the horizontal plane of the adjacent rod G, and thereby forming an inclined cam. It will be observed that the lower sides of the sails or wings rest upon and are supported by the rods K, and are thereby held at such an angle as to be operated upon by the wind.

Each sail or wing is provided with an arm, M, which projects from the lower side of the wing or sail and at right angles therefrom, and is thereby adapted to come in contact with the adjacent rod K when the wing or sail is turned in a horizontal position with its edge presented to the wind.

N represents a vertical operating rod,which passes through the tubular sleeve, and has its upper end connected to the wings or sails by means of rods 0.

From the foregoing description it will be understood that by drawing down upon the operating-rod N the outer end of the rods 0 will be projected radially from the center of the hub or spider, and consequently will cause the sails or wings to be moved outwardly on the radial arms and assume a position at an angle of about forty-five degrees. When in this position,the wings are presented to the wind and the wind-wheel will be rotated there by. If it be desired to cause the wind-wheel to cease to rotate, this may be accomplished by moving the operating -rod N upwardly thereby causing the rods 0 to draw the sails or wings inwardly toward the central hub or spider. As the inner ends ofthe said sails or wings come in contact with the upwardly-inclined portions of the rods K, the said sails or wings will be turned thereby upon the arms G until they assume a horizontal position, with their edges presented to the wind and their arms M bearing against the rods K, so as to retain the wings in a horizontal position. By moving the wings or sails in or out through only a portion of their adjustment the angle at which they are presented to the wind may be adjusted, and thereby the speed of the windwheel may be controlled.

The lower end of the tubular sleeve is pro vided with a horizontal miter gear-wheel, P, which meshes with asimilar wheel, R, secured to the inner end of the horizontal shaft S, that is journaled under the platform D. The said shaft is provided at its outer end with a crank, T, whereby a pump rod may be attached thereto if it is desired to operate a pump, and the said shaft S is also provided with a bandpulley, U, by means of which power may be transmitted to a suitable shaft by employing an ordinary endless belt.

Having thus described my invention, I claim- 1. In a wind-wheel, the combination of the radial arms, the wings or sails hinged thereon and adapted to slide longitudinally, and the inclines or cams bearing against the said wings to change the inclination thereof when they are moved longitudinally on the radial arms, for the purpose set forth, substantially as described.

2. In a wind-wheel, the combination of the radial arms, the sails or wings hinged or pivoted thereto and movable longitudinally thereon, the operating-rod N, the rods connecting the said operating-rod with the sails or wings, and means,substantia1ly as described,to change the inclination of the sails or wings as they are moved in or out upon the radial arms, sub stantially as set forth.

3. The combination, in a wind-wheel, of the radial arms, the sails or wings hinged or pivoted thereto and movable longitudinally thereon, the rods K, arranged substantially parallel ends of the said rods being inclined, and there-v I by adapted to turn the sails or wings to a horizontal position when they are moved inwardly, substantially as described.

4. The combination, in a wind-wheel, of the radial arms, the rods K, arranged substantially parallel therewith, and the sails or wings pivoted to the radial arms and bearing against the rods K, the said wings or sails having the arms M to strike against the said rods and support the wings or sails when turned to a horizontal position, substantially as described.

5. In a windmill, the combination of the tower or supporting frame, the wind-wheel journaled on the upper end thereof and having the depending tubular sleeve, the said wind-wheel being provided with the radial arms G, the wings or sails pivoted or hinged to the said arms and movable longitudinally thereon, the cams or inclines bearing against the inner ends of the wings or sails, for the purpose set forth, and the vertically-movable operating-rod N, extending through the tubular sleeve and connected to the sails or wings, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ORA S. WILLETT.
